What the thread found

• The post replacement procedure involves removing a locking screw to access side grub screws, then sliding the post out from the friction clamp
• The old bearings must be knocked out and replaced with new bushings during the post swap
• The existing arm post cap can be used as a tool to tap out the old bearings
• New bushings should fit neatly with the inner post tube inside the friction clamp block
• Tiffen released an upgraded thicker post for early G-50 models to address a known post issue
• The newer Clipper series features quick-release interchangeable arm posts that simplify future upgrades
• Bushings can be damaged if installed backwards or handled roughly, but small chips may not prevent functionality
• A bearing should be placed under the arm cap between the base and post during reassembly

Depends on

• Instructions are from memory and may be incomplete
• The process was performed on an older arm model and wear patterns may differ on newer units
• Tiffen was unavailable during the time of the discussion to provide official guidance
• The discussion does not specify which version of replacement kit was being used
• Success of the procedure depended on correcting the backward bushing installation
